I infer they aren't bulldozing a dike around the flat farmland to prevent runoff and allow the water to soak into the ground.
This will also reduce flooding from overloading the rivers with water.

You need some outflow to carry away salts. Otherwise, the water just evaporates and leaves the salt there, and eventually the land becomes unable to grow crops. This has historically been a serious problem in Mesopotamia, for example.

Earthen dikes and berms are a common feature around farmland in California.
